Fixes bug

This only happens when using SDL_RENDERER_SOFTWARE

When we create a texture from surface the texture access is static and sdl enables rle on the texture.

When we do SDL_UpdateTexture on that specified texture, sdl must lock the texture and unlock after updating pixels, else the program crashes.

The attached patch fixes this issue
